In this year's presidential campaign, Hillary Clinton has criticized the flood of so-called "dark money" that has dominated presidential politics since the Supreme Court's Citizens United decision. But is there a gap between the rhetoric and the reality?
A Center for Public Integrity investigation reveals that despite Clinton's statements about campaign finance reform, corporations, unions and dark money nonprofits have already poured millions of dollars into a network of Clinton-boosting political organizations. That's on top of the tens of millions an elite club of Democratic megadonors, including billionaire financiers George Soros and Haim Saban, have contributed to pro-Hillary super PACs.
Three cash-flush super PACs exist almost exclusively to strengthen Clinton's presidential effort.
Priorities USA Action, for example, has already spent millions helping Clinton secure the Democratic nomination. Ready PAC organizes and collects information from grassroots supporters. Correct the Record serves as a political SWAT unit attacking those who attack Clinton.

A fourth super PAC, American Bridge 21st Century PAC, aids Democratic candidates in general with opposition research — and was praised by Clinton at its outset.
These four core pro-Clinton super PACs have together raised $86 million, according to a Center for Public Integrity analysis of the most recent filings made with federal regulators. Of this haul, more than $10 million collectively comes from dozens of corporate or nonprofit sources, making tracking the money to a human source challenging.
The 2010 Citizens United v. Federal Election Commission ruling freed corporations, unions and certain nonprofits to raise and spend unlimited amounts of money to advocate for and against political candidates, and on balance, conservatives have embraced Citizens United much more than liberals, many of whom consider poorly regulated political money a poison that weakens democracy.
The high court's decision was prompted by a dispute over an anti-Clinton movie that conservative activist organization Citizens United wanted to broadcast during the final weeks of an election.
"Wouldn't you know that Hillary Clinton has become one of the greatest beneficiaries of the Citizens United Supreme Court decision," Citizens United President David Bossie said. "It is an irony that is not lost on me."
On the campaign trail, Clinton has assailed the system born out of this ruling.
In a speech last year, Clinton said, "We have to end the flood of secret, unaccountable money that is distorting our election, corrupting our political process, drowning out the voices and votes of people."
"As president, I'll appoint Supreme Court justices who recognize that Citizens United is bad for America. And if necessary, I'll fight for a constitutional amendment that overturns it," Clinton wrote in a CNN op-ed piece marking the 6th anniversary of the Citizens United decision.
"You're not going to find anybody more committed to aggressive campaign finance reform than me," Clinton said on Feb. 9 during a speech following the New Hampshire primary.
But she's also had to field questions from reporters and her rival Bernie Sanders about her own campaign finances.
